A method according to one embodiment includes removing a battery cover from an outer assembly of a lock device, removing a battery pack from the lock device in response to removing the battery cover, wherein removing the battery pack comprises disconnecting two electrical contacts of the battery pack from two corresponding electrical contacts of the lock device, and electrically coupling two electrical contacts of a retrofit assembly to the two corresponding electrical contacts of the lock device, wherein the retrofit assembly includes an energy storage device, a wireless power receiver configured to store generated power in the energy storage device, a boost regulator, and a microcontroller configured to adjust an output voltage of the boost regulator to indicate a power level of the energy storage device and a charging status of the energy storage device.

An electric lock includes a housing, a clutch mechanism and a manual control member. The housing is formed with a driving structure having a first inclined surface, a second inclined surface and a bottom surface. The clutch mechanism includes a driving member having a pushing structure, an elastic member arranged on the driving member for abutting against the driving structure, a rotating member having a pushed structure, and a motor for driving the driving member to rotate. The manual control member is connected to the rotating member. When the motor drives the driving member to rotate relative to the driving structure, the elastic member abuts against the first or second inclined surface to push the driving member to move toward the rotating member, so as to allow the pushing structure to abut against the pushed structure, in order to further drive the rotating member to rotate the manual control member.

A lock and method for locking including an electronic cylinder assembly that may be a direct replacement for a standard cylinder in a standard mortise type door lock housing. The cylinder assembly may include a first shaft rotatably mounted in the core and a second shaft rotatably mounted in the core and coaxial with the first shaft. A clutch is disposed on the first shaft and rotationally fixed to the first shaft but axially shiftable. The cylinder assembly also includes a slider with a finger, where the finger is engaged with the clutch, and a motor is configured to shift the slider axially between a first position and a second position. In the first position, the clutch is disengaged from the second shaft, and in the second position, the clutch is engaged with the second shaft, such that rotation of the first shaft causes rotation of the second shaft.

An electronic lock cylinder that may be a direct replacement for a European-style standard cylinder is disclosed. The lock cylinder may include a core, a first shaft rotatably mounted in the core, and a second shaft rotatably mounted in the core and coaxial with the first shaft. A first cam and a second cam may be each rotatably mounted in the core and coaxial with the first shaft. The first cam may include a first lug and the second cam may include a second lug, where the first lug and the second lug may each be coupled to a deadbolt. A clutch may be disposed on the first shaft and shiftable from a first position to a second position, and a motor may be disposed in the core and operatively coupled to the clutch and configured to shift the clutch from the first position to the second position. When the clutch is in the first position, the first shaft is operatively coupled to the first cam, and the second shaft is decoupled from both the first cam and the second cam, when the clutch is in the second position, both the first shaft and the second shaft are operatively coupled to the second cam.

A motorized lock assembly and a method of motorizing a lock installed in a door. The motorized lock assembly including a motorized drive assembly to be mounted to an interior side of the door in driving engagement with a bolt assembly of the lock. The motorized lock assembly also including a communications assembly to receive an instruction from a user and to direct an operation of the motorized drive assembly in response to the instruction from the user.

An intelligent door lock system coupled to a door at a dwelling. a door status device is at the dwelling. The door status device is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at the door. The lock device is coupled to the door status device and includes a bolt. An engine, an energy source and a memory are coupled together. A camera is coupled to or part of the intelligent door lock system. The camera is configured to record in response to door lock status.

A smart lock for securing a door is provided comprising: an actuator configured to actuate a lock mechanism between a locked and an unlocked position; a housing attachable to a first side of the door, retaining the lock mechanism and the actuator; a receiver configured to wirelessly receive a signal to control operation of the actuator; a key mechanism engageable with the lock mechanism so as to actuate the lock mechanism, the key mechanism for receiving a tail piece of a key cylinder; a handle mechanism engageable with the lock mechanism so as to actuate the lock mechanism; and a handle arranged to control operation of the handle mechanism extending from the housing on the first side of the door. The key mechanism and the handle mechanism are disengageable from the lock mechanism.

The present invention provides a motorised door lock assembly 10 in order for a user to be able to lock and unlock a door remotely and/or with a conventional key or with a thumb turn 22 from the inside. In particular, a user may decide to continue to use a key from the outside and the thumb turn (or an internal key mechanism) from the inside but at any stage the user (or a different user) may decide to operate the lock remotely. The motorised system may be activated by a number of actuators and, in particular, the motorised system may be activated by a remote key fob, a smart phone, an internally mounted push button or an external key pad. The assembly of the present invention is able to provide a continuous choice of all three methods (where permitted) without the risk of the lock becoming stuck in one position and without the user having to perform an elaborate particular sequence to operate the lock. The present invention is particularly for use with a Euro cylinder lock combined with a multipoint locking system 14 which thereby has operating limitations. The remotely activated motorised mechanism comprises a motor 50, a worm gear 52, a driven gear 54, rotary locking spindle engagement means 30 to transmit movement of the motor 50 to a rotary locking spindle of the cylinder lock, and a remote control actuator, the remotely activated motorised mechanism further comprising a multipoint monitoring system to determine an operational status of the multipoint locking mechanism and a rotary lock bolt monitoring system to determine an operational status of the lock bolt; and wherein the rotary locking spindle engagement means is arranged to directly engage a component of a thumb turn mechanism of a door lock.

An intelligent door lock system is coupled to a door at a dwelling. A door status device is at the dwelling. The door status device is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at the door. The lock device is coupled to the door status device and includes a bolt. Near field communication (NFC) is used to identify a lock device via an RF protocol. An engine, an energy source and a memory are coupled together. A camera is coupled to or part of the intelligent door lock system. The camera is configured to record in response to door lock status.

An intelligent unlocking device comprises a rear shell, a front shell, a motor assembly, a hollow rotating shaft, an adapting piece connected with a lock cylinder and the hollow rotating shaft, a manual rotating shaft, an inner bearing and a bearing support which are disposed around the manual rotating shaft, and an outer bearing. The bearing support and the outer bearing are disposed around an end of the manual rotating shaft. The intelligent unlocking device is silent and free of noises in use, and convenient to assemble and disassemble, intelligent unlocking can be achieved without replacement of a whole door lock, and costs are reduced for users.
